[Pathogenesis of migraine].
The extracranial and digital blood flow was examined in 60 patients with migraine and 15 healthy probands. The reaction of the extracranial vessels was evaluated in the patients with migraine in the interparoxysmal period, as compared with the control healthy individuals exposed to stress stimuli (local cooling, doing mental arithmetics, Valsalva's test), or given electrothermal bath or nitroglycerin. The existence of spontaneous fluctuations of the extracranial blood flow in the migraine patients is demonstrated. It has been found that in patients with the classical form of migraine the pain paroxysms are combined with an increase of the extracranial and a diminution of the digital blood flow.
